public class Cache71Dialect
extends Dialect
```
Caché 2007.1 dialect.

This class is required in order to use Hibernate with Intersystems Caché SQL. Compatible with Caché 2007.1.

<h2>PREREQUISITES</h2> These setup instructions assume that both Caché and Hibernate are installed and operational. <br> <h2>HIBERNATE DIRECTORIES AND FILES</h2> JBoss distributes the InterSystems Cache' dialect for Hibernate 3.2.1 For earlier versions of Hibernate please contact <a href="http://www.intersystems.com/support/cache-support.html">InterSystems Worldwide Response Center</A> (WRC) for the appropriate source files. <br> <h2>CACHÉ DOCUMENTATION</h2> Documentation for Caché is available online when Caché is running. It can also be obtained from the <a href="http://www.intersystems.com/cache/downloads/documentation.html">InterSystems</A> website. The book, "Object-oriented Application Development Using the Caché Post-relational Database: is also available from Springer-Verlag. <br> <h2>HIBERNATE DOCUMENTATION</h2> Hibernate comes with extensive electronic documentation. In addition, several books on Hibernate are available from <a href="http://www.manning.com">Manning Publications Co</a>. Three available titles are "Hibernate Quickly", "Hibernate in Action", and "Java Persistence with Hibernate". <br> <h2>TO SET UP HIBERNATE FOR USE WITH CACHÉ</h2> The following steps assume that the directory where Caché was installed is C:\CacheSys. This is the default installation directory for Caché. The default installation directory for Hibernate is assumed to be C:\Hibernate. <p/> If either product is installed in a different location, the pathnames that follow should be modified appropriately. <p/> Caché version 2007.1 and above is recommended for use with Hibernate. The next step depends on the location of your CacheDB.jar depending on your version of Caché. <ol> <li>Copy C:\CacheSys\dev\java\lib\JDK15\CacheDB.jar to C:\Hibernate\lib\CacheDB.jar.</li> <p/> <li>Insert the following files into your Java classpath: <p/> <ul> <li>All jar files in the directory C:\Hibernate\lib</li> <li>The directory (or directories) where hibernate.properties and/or hibernate.cfg.xml are kept.</li> </ul> </li> <p/> <li>In the file, hibernate.properties (or hibernate.cfg.xml), specify the Caché dialect and the Caché version URL settings.</li> </ol> <p/> For example, in Hibernate 3.2, typical entries in hibernate.properties would have the following "name=value" pairs: <p/> <table cols=3 border cellpadding=5 cellspacing=0> <tr> <th>Property Name</th> <th>Property Value</th> </tr> <tr> <td>hibernate.dialect</td> <td>org.hibernate.dialect.Cache71Dialect</td> </tr> <tr> <td>hibernate.connection.driver_class</td> <td>com.intersys.jdbc.CacheDriver</td> </tr> <tr> <td>hibernate.connection.username</td> <td>(see note 1)</td> </tr> <tr> <td>hibernate.connection.password</td> <td>(see note 1)</td> </tr> <tr> <td>hibernate.connection.url</td> <td>jdbc:Cache://127.0.0.1:1972/USER</td> </tr> </table> <p/> <b>NOTE:</b> Please contact your administrator for the userid and password you should use when attempting access via JDBC. By default, these are chosen to be "_SYSTEM" and "SYS" respectively as noted in the SQL standard. <br> <h2>CACHÉ VERSION URL</h2> This is the standard URL for the JDBC driver. For a JDBC driver on the machine hosting Caché, use the IP "loopback" address, 127.0.0.1. For 1972, the default port, specify the super server port of your Caché instance. For USER, substitute the NAMESPACE which contains your Caché database data. <br> <h2>CACHÉ DIALECTS</h2> Choices for Dialect are: <br> <p/> <ol> <li>org.hibernate.dialect.Cache71Dialect (requires Caché 2007.1 or above)</li> <p/> </ol> <br> <h2>SUPPORT FOR IDENTITY COLUMNS</h2> Caché 2007.1 or later supports identity columns. For Hibernate to use identity columns, specify "native" as the generator. <br> <h2>SEQUENCE DIALECTS SUPPORT SEQUENCES</h2> <p/> To use Hibernate sequence support with Caché in a namespace, you must FIRST load the following file into that namespace: <pre> etc\CacheSequences.xml </pre> For example, at the COS terminal prompt in the namespace, run the following command: <p> d LoadFile^%apiOBJ("c:\hibernate\etc\CacheSequences.xml","ck") <p> In your Hibernate mapping you can specify sequence use. <p> For example, the following shows the use of a sequence generator in a Hibernate mapping: <pre> <id name="id" column="uid" type="long" unsaved-value="null"> <generator class="sequence"/> </id> </pre> <br> <p/> Some versions of Hibernate under some circumstances call getSelectSequenceNextValString() in the dialect. If this happens you will receive the error message: new MappingException( "Dialect does not support sequences" ). <br> <h2>HIBERNATE FILES ASSOCIATED WITH CACHÉ DIALECT</h2> The following files are associated with Caché dialect: <p/> <ol> <li>src\org\hibernate\dialect\Cache71Dialect.java</li> <li>src\org\hibernate\dialect\function\ConditionalParenthesisFunction.java</li> <li>src\org\hibernate\dialect\function\ConvertFunction.java</li> <li>src\org\hibernate\exception\CacheSQLStateConverter.java</li> <li>src\org\hibernate\sql\CacheJoinFragment.java</li> </ol> Cache71Dialect ships with Hibernate 3.2. All other dialects are distributed by InterSystems and subclass Cache71Dialect.

    Overrides:
    
    supportsLimitOffset in class Dialect
    
    Returns:

    Does the <tt>LIMIT</tt> clause come at the start of the <tt>SELECT</tt> statement, rather than at the end?
    
    Overrides:
    
    bindLimitParametersFirst in class Dialect
    
    Returns:
    
    true if limit parameters should come before other parameters
  - useMaxForLimit
```
public boolean useMaxForLimit()
```
    Description copied from class: Dialect
    
    Does the <tt>LIMIT</tt> clause take a "maximum" row number instead of a total number of returned rows? <p/> This is easiest understood via an example. Consider you have a table with 20 rows, but you only want to retrieve rows number 11 through 20. Generally, a limit with offset would say that the offset = 11 and the limit = 10 (we only want 10 rows at a time); this is specifying the total number of returned rows. Some dialects require that we instead specify offset = 11 and limit = 20, where 20 is the "last" row we want relative to offset (i.e. total number of rows = 20 - 11 = 9) <p/> So essentially, is limit relative from offset? Or is limit absolute?
    
    Overrides:
    
    useMaxForLimit in class Dialect
    
    Returns:
    
    True if limit is relative from offset; false otherwise.
  - getLimitString
```
public String getLimitString(String sql,
                             boolean hasOffset)
```
    Description copied from class: Dialect
    
    Apply s limit clause to the query. <p/> Typically dialects utilize variable limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest since we will just be using placeholders. <p/> Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method and Dialect.getLimitString(String, int, int).
    
    Overrides:
    
    getLimitString in class Dialect
    
    Parameters:
    
    sql - The query to which to apply the limit.
    
    hasOffset - Is the query requesting an offset?
    
    Returns:
    
    the modified SQL
  - registerResultSetOutParameter

    Description copied from class: Dialect
    
    Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet by position. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.

    Overrides:
    
    getResultSet in class Dialect
    
    Parameters:
    
    ps - The callable statement.

```
    Description copied from class: Dialect
    
    Build an instance of a SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes. <p/> When Dialect.buildSQLExceptionConverter() returns null, the default SQLExceptionConverter is used to interpret SQLState and error codes. If this method is overridden to return a non-null value, the default SQLExceptionConverter will use the returned SQLExceptionConversionDelegate in addition to the following standard delegates: <ol> <li>a "static" delegate based on the JDBC 4 defined SQLException hierarchy;</li> <li>a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType</li> </ol> <p/> It is strongly recommended that specific Dialect implementations override this method, since interpretation of a SQL error is much more accurate when based on the a vendor-specific ErrorCode rather than the SQLState. <p/> Specific Dialects may override to return whatever is most appropriate for that vendor.
    
    Overrides:
    
    buildSQLExceptionConversionDelegate in class Dialect
    
    Returns:
    
    The SQLExceptionConversionDelegate for this dialect
  - getViolatedConstraintNameExtracter
```
public ViolatedConstraintNameExtracter getViolatedConstraintNameExtracter()
```
    Specified by:
    
    getViolatedConstraintNameExtracter in interface ConversionContext
    
    Overrides:
    
    getViolatedConstraintNameExtracter in class Dialect
  - supportsEmptyInList
```
public boolean supportsEmptyInList()
```
    Description copied from class: Dialect
    
    Does this dialect support empty IN lists? <p/> For example, is [where XYZ in ()] a supported construct?
    
    Overrides:
    
    supportsEmptyInList in class Dialect
    
    Returns:
    
    True if empty in lists are supported; false otherwise.
  - areStringComparisonsCaseInsensitive
```
public boolean areStringComparisonsCaseInsensitive()
```
    Description copied from class: Dialect
    
    Are string comparisons implicitly case insensitive. <p/> In other words, does [where 'XYZ' = 'xyz'] resolve to true?
    
    Overrides:
    
    areStringComparisonsCaseInsensitive in class Dialect
    
    Returns:
    
    True if comparisons are case insensitive.
  - supportsResultSetPositionQueryMethodsOnForwardOnlyCursor
```
public boolean supportsResultSetPositionQueryMethodsOnForwardOnlyCursor()
```
    Description copied from class: Dialect
    
    Does this dialect support asking the result set its positioning information on forward only cursors. Specifically, in the case of scrolling fetches, Hibernate needs to use ResultSet.isAfterLast() and ResultSet.isBeforeFirst(). Certain drivers do not allow access to these methods for forward only cursors. <p/> NOTE : this is highly driver dependent!
    
    Overrides:
    
    supportsResultSetPositionQueryMethodsOnForwardOnlyCursor in class Dialect
    
    Returns:
    
    True if methods like ResultSet.isAfterLast() and ResultSet.isBeforeFirst() are supported for forward only cursors; false otherwise.
